Not Reef Tank Suitable
Not Suitable for Fish-Only Tank
Range: Western Atlantic Ocean: Florida, Caribbean, and the Bahamas.
Natural Environment: Inhabits caves and/or found on reef flats.
Aquarium Suitability: May arrive on the bottom or lower sides of live rock or large rocky coral specimens.
Furthermore, keep in mind, if a hitchhiker sponge arrives attached to a coral specimen or live rock, it is reasonable to assume that at one time it was subjected to 'air' when the specimen or rock was harvested/shipped/transferred to various storage areas, thereby endangering the ongoing lifespan of the hitchhiker sponge, as it should never to subjected to air! Therefore the ongoing culture of hitchhiker sponges is dismal at best!
Best left in the wild.
